File extention check before upload the file class, calling, spring, before, public

amy

Hi all,
I am very new to spring mvc. I want to check the file before the file upload. If anyone can help me about the right way to do it.
thanx

What api you are using to upload the files?

public static Listlt;Stringgt; uploadFile(MultipartfromServletRequest req, String location)

from my controller i am calling this method to upload and i am also using
lt;bean id=quot;maxUploadSizeExceededExceptionHandlerquot; class=quot;com.ranker.web.core.exceptionHandler.MaxUpl  oadSizeExceededExceptionHandlerquot;/gt;
to check the file size error.

you need more information about it?
